Hi Ingo,
We are running into a similar problem. This is happening intermittently.
When I try to connect from Information Design tool, I get this below error.
I see same WSAETIMEDOUT error even from the Roles tab in Authentication->SAP area in CMC. Our Entitlement users are intact and nothing changed either on BOBJ or BW systems. After 2-3 tries it starts to work. But after a few minutes I again see this error. Please advise. Thank you very much.
I typed * in the Name/IP Address of our systems for confidentiality in the message below.
